Greater Korean Republic

The Greater Korean Republic (GKR) was a Korean superstate that united North Korea and South Korea in 2013 and went on to form an empire the size of the Empire of Japan in 1942, occupying Japan, Indonesia, the Philippines, Malaysia. Thailand, Vietnam, Cambodia, Laos, Burma, Papua New Guinea, Brunei, East Timor, and Singapore.

History
Following the death of Supreme Leader Kim Jong-il in December 2011, Kim Jong-un became the new leader of North Korea. He decided to end hostilities with South Korea and embraced a "one nation, two systems" policy that unified Korea while utilizing the military strength of the north and the economic strength of the south. With the armistice peacefully ending between the two countries, North and South Korea became a unified Korean nation that embraced Korean nationalism. The GKR was formally united in 2015 after South Korea blamed the United States for the global economic downturn, causing its withdrawal from the region. With the withdrawal of the United States, the Greater Korean Republic proceeded to become a major power in the Far East, and Japan became their rival. Tens of thousands of ethnic Koreans were killed in Japan, resulting in a 2018 invasion of Japan by Korea that ended in Korea's conquest of the country.

In the following years, the Greater Korean Republic proceeded to conquer several countries in Southeast Asia, forming an empire nearly the size of the Empire of Japan during World War II in 1942. The republic provided economic security to East Asia, leading to several of the countries in the region voluntarily joining the GKR, sparing them the expenses of waging war against them.

In 2025, the Greater Korean Republic made a daring move by using a GPS satellite to use an electromagnetic pulse (EMP) weapon to destroy the United States' defenses in preparation for an invasion. They launched an amphibious invasion that took over Hawaii, and they pushed up to the Mississippi River, which they filled with radiation in Operation Water Snake to divide the country. The GKR was powerful, but the American Resistance pushed them back at the Battle of San Francisco; eventually, the GKR was pushed back, but they were able to take over Philadelphia and other areas of the East Coast.
